ADP1720It is a high voltage, micropower,Low dropout linear regulator, operates over a very wide input voltage range (4 V to 28 V) and can deliver up to 50 mA of output current. With a quiescent supply current of only 28 μA and a micropower shutdown mode, the device is ideal for applications requiring low quiescent current.
The ADP1720 uses fixed 3.3 V and 5.0 V output voltages and is available in an adjustable voltage version that allows the output to be set to any value between 1.225 V and 5.0 V. An enable feature is provided that allows external circuitry to turn the output of the ADP1720 on or off. For automatic start-up, the enable pin (EN) can be connected directly to the input rail.
The ADP1720 is optimized for stable operation using a small 1 μF ceramic output capacitor, resulting in good transient performance while minimizing the board footprint.
The ADP1720 operates over the –40°C to +125°C temperature range and uses current-limiting and overtemperature protection circuitry to prevent damage to the device under adverse conditions.
The ADP1720 is available in a small, thermally enhanced MSOP package that provides a compact solution with low thermal resistance.
